Here is what the above code is Doing:
1. We create an ArrayList of String type and add some elements to it.
2. We create a copy of the original ArrayList using the copy constructor.
3. We add some more elements to the original ArrayList.
4. We print the original ArrayList and the copy ArrayList.
Original ArrayList: [A, B, C, D, E]
Copy of ArrayList: [A, B, C, D, E]
Original ArrayList after copy: [A, B, C, D, E, F, G]
Copy of ArrayList after original is modified: [A, B, C, D, E]
